Definition of an Atom

An atom is the basic unit of a chemical element, consisting of a dense central nucleus surrounded by a cloud of negatively charged electrons. The nucleus contains positively charged protons and uncharged neutrons, while the electrons are in constant motion around the nucleus. The number of protons in the nucleus determines the element's atomic number, which in turn defines the chemical properties of the element.

Atoms are incredibly small, with typical sizes on the order of 100 picometers (10^-12 meters) and have a mass of about 1.67 x 10^-27 kilograms The behavior of atoms is governed by the laws of quantum mechanics, and their interactions with each other form the basis of chemical reactions and the structure of matter.

In summary, an atom is the fundamental building block of matter, composed of a nucleus containing protons and neutrons, surrounded by a cloud of electrons, and is the basic unit of a chemical element
